Abstract
A production log which is developed by data recorded in a downhole memory in a well tool as a function of real time and data recorded at the earth's surface as a function of time and merged to produce a log of data as a function of depth. The well tool is moved with a velocity selected to obtain fluid velocity data as a function of time and the velocity of the tool is measured at the earth's surface as a function of time. The functions of time are on a common basis so that a true velocity of fluid flow can be obtained as a function of depth.
